Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light influencing devices for photography are cumbersome to assemble and transport due to the need for separate fastening elements, such as screws, which complicates outdoor photo shoots where quick setup is required.
Innovation Solution
A device with a support frame comprising stretcher rods and spreader rods with concave receiving surfaces allows for easy assembly and disassembly, eliminating the need for additional fastening elements by using the elasticity of the covering and spreader rods to secure the stretcher rods, and features a carbon fiber spreader rod for stability and ease of handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If separate fastening elements such as screws are used to connect transversal tubes to peripheral tubes, then structural stability is improved, but assembly time and device complexity increase
Solution Approach 1:
The connection between transversal tubes and peripheral tubes is achieved by integrating the connection function directly into the tube structure itself. The tubes are designed with complementary geometric features that interlock without requiring separate fastening elements, thereby reducing assembly time while maintaining structural stability through the inherent geometric interlocking mechanism.
Solution Approach 2:
The support frame is designed as a telescopic structure where transversal tubes can be inserted into and nested within peripheral tubes. This nesting arrangement allows for quick assembly and disassembly while maintaining structural integrity through the nested geometric configuration, eliminating the need for separate fastening elements.
2Reliability
If separate fastening elements such as screws are used to connect tubes, then connection reliability is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The connection function is merged into the tube structure itself through geometric interlocking features. This integration eliminates the need for separate fastening elements, reducing device complexity while maintaining connection reliability through the inherent geometric design that provides stable interlocking.
Solution Approach 2:
The tubes are designed to self-connect through their geometric features without requiring external fastening elements. The complementary shapes of the tubes enable them to interlock and secure themselves, simplifying the device structure while ensuring reliable connections through the self-service mechanism.
3Stability of the object's composition
If multiple separate fastening elements are used for assembly, then structural stability is improved, but ease of operation and portability worsen
Solution Approach 1:
The connection functionality is merged into the tube structures themselves through geometric interlocking features. This eliminates the need for multiple separate fastening elements, making the device easier to assemble and disassemble for portability while maintaining structural stability through the integrated geometric design.
Solution Approach 2:
The support frame is segmented into modular tube sections that can be easily connected and disconnected. Each tube segment is designed with geometric features that enable simple interlocking, facilitating quick assembly and disassembly for transport while maintaining overall structural stability through the modular segmented design.
